About Induction Hearing Loop Systems
Home Induction Loop systems transmit the signal from a TV or home theater through an easily installed WIRED LOOP or a small CUSHION LOOP. Commercial loops use a permanently installed wire similar to the home loop for larger buildings such as houses of worship or auditoriums. Loops can also be installed at counters for most types of customer transactions. There is a superior loop solution for any facility, public or private, where sound is broadcast.
The signal is picked up by a small coil of wire inside the hearing aid, called a T-Coil. The T-Coil uses no electricity so it doesn’t affect the battery life of the hearing aid. The signal from the loop plays through the customized hearing aid programming. The sound is mixed and adjusted by the hearing aid to compensate for the users hearing loss, giving as close to true sound reproduction as possible with an assistive device.
T-Coil equipped hearing aid users with loop systems enjoy crystal clear customized sound without wearing another complicated device that needs charging or batteries. An Induction Loop system eliminates background noise and echo by sending the audio signal directly to the hearing aid without extra equipment or devices to connect or put over the ears. To the listener, it sounds like the speaker is sitting on their shoulder, talking directly in their ear!
The loop system consists of a microphone to pick up the spoken word, an amplifier to process the signal that is then sent through the induction loop and a wire placed around the perimeter of a room or sanctuary to act as an antenna that radiates the magnetic signal to the hearing aid. It results in improved speech understanding because the listener receives a clear signal without any background noise. About 60 percent of hearing aids have this antenna, also known as the telecoil or T-coil, and can pick up the sound.
Hearing Loops are more likely to be used than other assistive systems because they do not require wearing or checking out something that identifies the user as different. They can make a profound difference in the lives of the hard of hearing – anywhere that sound is broadcast – they work in:
- Living rooms
- Senior facility common areas
- Bank and pharmacy windows
- Movie theaters
- Concert halls
